View of the falls between Lewiston and Auburn

Among the larger rivers in New England, the Androscoggin is by far the most unnavigable by vessels of any size, which explains why it was explored and permanently settled by white people later than other rivers in the region—and, more significantly, why it became so heavily industrialized. This view of the falls between Lewiston and Auburn is taken from Walter Wells' 1869 volume, The Water Power of Maine.
